Maintenance and Cleaning Filter Instructions Filter prevents dust from accumulating on the optical elements inside the projector. Should the filter becomes clogged with dust particles, it will reduce cooling fans' effectiveness and may result in internal heat buildup and adversely affect the life of the projector. This projector has an electrically operated filter which helps you to replace the filter easily. The projector monitors the condition of the filter at all time and replaces a filter with a new one automatically when it detects the clogging. If the projector reaches a time set in the timer setting (p.56), a Filter replacement icon (Fig.1) appears on the screen and the WARNING FILTER indicator on the top control lights up. When you see this icon, replace the filter as soon as possible (p.53). If the filter is out of scroll and the projector reaches a time set in the timer setting, Fig.2 appears on the screen, indicating that the filter cartridge replacement is necessary. Fig.1 Filter replacement icon Fig.2 When the scroll counter is counted down to 0, the Last scroll icon (Fig.3) appears on the screen, indicating that there is no scroll left in the filter cartridge (p.56). Fig.3 Last scroll icon If the projector detects that the filter is clogged and no scroll is left in the filter cartridge, a Filter cartridge replacement icon (Fig.4) appears on the screen and the WARNING FILTER indicator on the top control lights up. When you see this icon, replace the filter cartridge (p.61) and reset the Filter counter (p.62) and the Scroll counter (p.62). When the filter is being scrolled using the Filter control function in the setting menu (p.53), a Filter replacement icon and "Please wait..." message (Fig.5) appear on the screen and the WARNING FILTER indicator blinks slow (approx. 2 seconds ON, 2 seconds OFF). (p.72) Fig.4 Filter cartridge replacement icon Fig.5 Filter replacement icon and "Please wait..." message. The WARNING FILTER indicator blinks fast when the projector detects an abnormal condition, the filter cartridge is not installed properly, or the filter scroll is not working properly. (p.73) Note: • Fig.1, Fig.2, Fig.3, Fig. 4 and Fig.5 will not appear when the Display function is set to "Off" (p.46), during "Freeze" (p.25) or "No show" (p.26). • The filter cannot be rewound. • The filter can be scrolled 9 times since the filter cartridge has 10 scrolls. • The filter cartridge is disposable. Do not clean and reuse the filter cartridge. • Do not expose the filter cartridge to water or liquid, or it may cause a breakdown. • Replace the filter cartridge after all the scroll is used up. If you replace the filter cartridge when there are some scrolls left in the filter cartridge, the filter counter and the scroll counter do not recognize the correct number of remaining scrolls and the reset function cannot work properly. It may cause a breakdown. • Do not use the filter cartridge with other projector. The filter counter and the scroll counter do not recognize the correct number of remaining scrolls of the used filter cartridge and the reset function cannot work properly. It may cause a breakdown. 60 • Make sure that the projection lamp is turn off when you are replacing the filter cartridge. If you replace the filter cartridge when the projection lamp is turn on, the projector will be shut down automatically for safety purpose. • Do not forget to reset the filter counter and the scroll counter in the setting menu after replacing the filter cartridge. If you forget to reset the filter counter and the scroll counter, the projector cannot recognize the correct number of remaining scrolls and may cause a breakdown. • When the projector is kept used for 3 minutes without getting the filter cartridge replaced after the Fig.4 appears on the screen, the projector is turned off automatically to prevent the damage of optical components.
